The defence secretary, John Healey, has urged Nigel Farage to provide transparency about the £5m gift he received from a billionaire businessman, in particular over whether any of the sum could have been linked to Russia-connected profits.

In a letter to the Reform UK leader, Healey also asked him to address the possibility that the war against Iran might boost the revenues of AML Global, an aviation fuel company owned by Christopher Harborne, who gave Farage the £5m in 2024. Farage initially supported the US-Israeli attacks on Iran.
